Note: This building once served as the Chickasaw National Capitol when it was originally built. The building was designed to overlook the town on a grand hill . In 1910, Johnston County purchased the structure for $15,000 and it served as the county courthouse until 1992 when the Chickasaw Nation bought in back for $575,000. Johnston County finished its current courthouse, down the hill from this one in 1993. Because this courthouse was built in 1896, this is one of the oldest structures in the state that has served as a county courthouse.
